Sometimes I wish I could sleep

I really wish I can sleep like a normal person.

I don't want to rely on sleeping pills. I just want to fall asleep.

But every now and then, I stare into the ceiling. I feel tired, I close my eyes but when I open them, i feel sad to realize only 20 ~ 30 mins have passed. Yet, I still feel so awake ... and once again, I stare into the ceiling. I hear the fan, 'Train' singing on itunes, a few cars driving and my heart beating. The room is black.

Why do I suffer? I hate this feeling. I want to sleep normally, so I don't feel tired tomorrow.

Damm.
